A Local Law to amend the New York city plumbing code, in relation to the drainage location of certain building roofs

This bill would require that roofs on covered buildings drain onto a permeable surface in accordance with DEP rulemaking. Covered buildings would be residential buildings that are served by the combined sewer system and located on lots where the front yard area is at least 20 percent of the lot coverage area. Buildings in the 10-year rainfall flood risk area and certain other buildings would be exempt.
